The 3D buildings and objects on top of the terrain flash on and off several times per second, as if the GPU couldn't decide whether to draw them or not... Tried vsync on and off, MSA on and off, it makes no difference.
Anyone else has the same problem? Any idea how to correct it?

GPU is a Nvidia GTS450, drivers 270.61, quad core CPU

Ciao,

EDIT: problem solved by reinstalling

Its not the subject but as I see you've got a Nvidia 270.61 DON'T update to 280 (275.33 is okay) because you'll probbly have random freezes -> http://www.benchmarksims.org/forum/showthread.php?5314-Spontaneous-sim-freezes-during-missions.-

I'm running a GTX 460 and can confirm that the 275.33 drivers work fine.

thx guys; as a matter of fact I had dowloaded the new drivers and was on the point of installing them

Interesting. I have been using the new 280.26 drivers since release. Been running BMS for hours on end without these freezes. I DID have several freezes when hosting a specific ARMA 2 mission last week or two; nothing like that with BMS.
